Unfulfilled predictions
Predictions such as the following have appeared in various Watchtower publications: [56]
- 1907: Armageddon will culminate in the year 1914. [57]
- 1917: In 1918, God would begin to destroy churches "wholesale" and church members by the millions. [58]
- 1922-1923: The resurrection of the dead would occur in 1925. [59] In preparation for the 1925 date, the Watchtower Society acquired a property in California, and built a mansion on it. The property was to house people such as Abraham, Moses, David, and Samuel, whom they thought would be resurrected to life in 1925.
- 1938: In 1938, Armaggedon was too close for marriage or child bearing. [60]
- 1941: There were only "months" remaining until Armageddon. [61]
- 1942: Armageddon was "immediately before us." [62]
- 1969: Human existence would not last long enough for young people to grow old; the world system would end "in a few years". Young Witnesses were encouraged not to bother pursuing tertiary education for this reason. [63]
- 1969: Christ's thousand-year reign would begin in 1975. [64] There was a considerable amount of related speculation in Watchtower publications in the decade or so leading up to 1975. [65]
- 1984: There were "many indications" that "the end" was closer than the end of the 20th century. [66]
